Olympic swimming champion Evgeny Rylov suspended for nine months after attending Vladimir Putin-hosted rally

Swimming's world governing body FINA has suspended Russian Olympic gold medallist Evgeny Rylov for nine months after he attended a rally in support of Russia's military campaign in Ukraine, in a move that drew an angry reaction from the Kremlin.

The 25-year-old, who won gold in 100 and 200 metres backstroke events at last year's Tokyo Olympics, was among several athletes who attended a massive rally at Moscow's Luzhniki stadium last month hosted by President Vladimir Putin.

Rylov and other athletes wore the letter 'Z' on their outfit, an identifying symbol used by supporters of what Russia calls its "special military operation" in Ukraine.

FINA said the suspension came "following Mr. Rylov's attendance and conduct at an event held at the Luzhniki Stadium in Moscow".

Rylov, who also lost his sponsorship deal with swimwear maker Speedo over his presence at the rally, told Sport Express newspaper his lawyers were reviewing the case but it was still unclear whether they would appeal his suspension.

The Kremlin said FINA's decision showed the "politicization of sport".

"We believe this is absolutely contrary to the ideas of sport," Kremlin spokesman Dmitry Peskov told reporters on a conference call on Friday.

"When the strongest [competitors] lose the opportunity to participate, this ultimately harms international federations and international competitions."

FINA has already cancelled all its events that were set to take place in Russia and has barred Russian and Belarusian athletes and officials from taking part in its competitions until the end of the year.
